SCBAPEB LOADING APPARATUS.

Application llled December 29, 1922, Serial llo. 009,570. Renewed September 7, 1926.

This invention relates to improvements in apparatus for handling loose material, and more particularly to draft operated scraper devices adapted to gather and transport loose material forloading into a car or the like. The apparatus herein shown and described is particularly adapted for use in mines, or under similar conditions where working space is limited, as for instance, in the room and pillar system of coal mining, in which coal is'v transported from the working face in a mine room by mea'ns of a draft operated scraper, to be loaded in mine cars mounted on tracks in an entry or gallery.

'The principal object of the invention is to provide a novel construction of loading chute adapted to extend over a mine car, upon which chute the scraper may be moved into position over the car so asto be vunloaded therein. A further object is to provide a novel arrangement ofphoisting device or mechanism for actuating and controlling the draft ropes, mounted on the loading chute. A further object is to provide means for transporting the entire mechanism so as to be readily moved from place to place in the mine. V y

The invention may be best understood by reference to the accompanying drawings and the description relative thereto, disclosing one form lof apparatus in which my inveny tion is embodied.

Figu

taken on line 12- 12 of Figure 10. In the embodiment illustrated, the loading chute comprises an inclined runwa 10 adapted to have contact with the groun an re 12 is a sectional view of the truck` clined runway 10. In the form shown, these y guideways are continued along opposite sides of the loading platform 11 but at relatively greater height than the portions 14,14 of said guideways, as indicated at 15, 15.

The entire chute is preferably mounted for movement on the mine floor and tothis end tle su porting member 12 is provided with suitab e wheels 16, 16 adapted to engage the ground, as shown in Figures 1 and 7. In the form shown these wheels are journaled in a frame memberv 17 (see Figure 7) which is connected to the supporting `member l12 by means of an expansible joint, which in the present instance, comprises a jack member 18, having an upper lportion thereof threaded in a stud 19 on the supporting member 12 and the lower portion thereof threaded in the frame member 17. The jack member 18 may. be rotated in the usual manner to adjust the heightof the frame member1'12 with respect to the ground.

The supporting member 13 connected with the inclined portion 10 of the ychute is provided at its lower end with supporting wheels 20, 20, mounted on a frame member 21. In this instance the frame member 21 is pivotally connected to the supporting member 13, so that the wheels may readily adjust themselves with the inequalities of the floor. The supporting member 13 also preferably provided with an'extensiblc connection which, in this instance, comprisesl a rotatable jack mcfnber 22having upper' and lower threaded portions engaging respectively upper and lower portions, 23 and 24, of the member 13. Power devices forcontrolling and actuating a draft operated scraper are mounted on the chute. These power devices are preferably arranged at the far end of the loading platform 11, opposite the inclined runway 10, and in the form shown are mounted onr the supporting member 12. Any suitable power devices and operating mechanism may be provided for this purpose, itl being understood that it is preferable to provide two winding drums, one for the head rope of the scraper, to provide a forward draft therefor and another fory the tail rope to provide a rearward draft therefor. In the form shown this mechanism includes a winding drum 30 loosely mounted on a shaft 31, and another drum 32 loosely mounted on a parallel shaft 33. These drums are driven by .a

motor 34 through suitable gearing, such as f an armature pinion `35 and gear 36 on the stub shaft 37. A second gear 38 rotates with the gear 36 and is meshed with the gear 39 keyed to the shaft 33 on which the drum 32 is mounted as aforesaid. Said drum may be operai ively connected to the shaft 33 through a sliding clutch 40 or its equivalent. In the present instance the clutch shown is of the cone type. The gear 39 on the shaft 33 is meshed with the gear 41 on the shaft 31 and this shaft in turn may be operatively connected to the second drum 30 by means of a second clutch 42. It will be observed that the drums 30 and 32 will be rotated in opposite directions owing to the meshed relationship ofthe driving gears 39 and 41 which drive the respective drums. The motor, drums and gearing are arranged on axes' of revolution which are substantially in vertical alignment with each other so as to provide a particularly compact operating mechanism.

The use of the chute will be best understood by referring to the Figures 3, 4, 5 and 6. In Figures 3 and 4 the scraper is indicated at 50 and is provid-ed with a head rope 51 and a tail rope 52. This scraper is adapted to be reciprocably moved by the head and tail ropes which may be trained about suitable guide sheaves and anchored in the mine room in any suitable manner. The head rope 51 passes over a roller 32a and is wound on the lower drum 32, while thel tail rope passes over a roller 30L and is wound over the upper drum 30. Itwill be understood that the tail rope passes from its drum into the room and about suitable sheaves,` so as to provide arearward draft on the scraper to pull it backwardly into position to gather a load,

whereas the head-rope 51.15.y attached to the front end of the scraper and is arranged to exert a forward draft thereon. The guiding means which controlthe movement of the scraper are not shown, as they formno part of the invention, and may be arranged in any suitable manner so as to direct the forward movement thereof into the loading runway. 'lhis chute is arranged so as to extend -over the mine cars or the like with the load,-

ing platform 11 directly over the tracks in posit'on to permit the scraper'to be emptied into the ,car thereunder when, said scraper is on the loading platform;

In the form shown the scraper 50 is of the bottomless type as'indicated in Figure 3 and a suitable opening 11a is formed in the loading platform 11 so as to permit the material to be dropped through said platform into the car when the scraper is in position over said opening. As for the broader features of my invention, however, it will be understood that other forms of Scrapers may be used, and various arrangements of dumping means may be provided, as desired.

The chute may be rigidly held in any desired position over the car by suitable means such as jacks 54, 54 engaging the upright member 12 and jacks 55, 55 engaging the sides 14 of the inclined portion 10. A suitable cross member or stop 56 is provided intermediate the chute opening 11 and the hoisting drums, so as to limit the movement of'lthe scraper together with the loose mate.- rial therein.

It will be observed in Figures 3 and 4 that the inclined portion of the chute extends into the neck of a mine room. It will be understood, that the entries in which the tracks are laid are usually as narrow as is consistent with mining conditions, so that the space for moving and transporting apparatus of the class described is generally quite limited.

Means for transporting the loading chute from place io place, as for instance, from one room neck to another, may comprise any suitable supporting device mounted on the track rails and adapted to be moved into supporting position underneath the loading plaiform 11. In the form illustrated in Figures 5 and 6. and 10 to 12, inclusive. l have, shown a truck indicated at 60 which is particularly adapted for this purpose. The truck com prises a frame 61 of any suitable construction provided with flanged wheels 62, 62 adapted to engage the track. The truck is provided with an extensible supporting device which is low enough to run under the chute when it is supported on the ground in the loading position and thereafter the extensible supporting device ma be elevated into position to engage and ralse the entire chute from the ground, as shown in Figure 6. In the present instance the extensible device comprises frame 66. as for instance a plura ity ofl vertically disposed guide pins 69, 69 extending downwardly through guide members 70, 70 mounted on the truck frame member 61. When in use, the truck is moved into position underneath the chute and the liack 63 is then actuated to lift theentire chute out of engagement with the ground, in

which position it is then supported onthe turntable, as indicated in full lines in Figure 5. The truck, together with the chute, may then be moved along the track into a second position, as indicated in dotted lines in Figure 5, and` the entire chute may then be swung about on the turntable 67 into substantially longitudinal alignment with the track, as is aslo indicated at Figure 5, in which latter position the chute may be readily transported along the track by moving the truck therealong in any desired manner. The chute may then be positioned in a new f room neck by reversing the sequence of movements described above and illustrated in Figure 5.4

It will be noted that the chute is arranged and constructed so that the inclined runway l() thereof will be substantially counterbalanced by the operating mechanism carried on the supporting member 12 whichy is on the opposite side'of the track and therefore on the opposite side Aof the point of pivotal movement of the chute when it is pivotally swung on the supporting truck 60.v

My invention is not limited to the particular form of truck shown for transporting the loading chute, it being understood that similar elevating and turntable devices may be mounted either on a mine car or on a relatively small mining locomotive, as for instance. a locomotive of the gathering type, upon which such elevating and turntable devices could be readily installed, if desired. lYith reference to the loading' chute itself, it will also 'be understood that while I have shown a specified form in'which my'invention may be embodied, other forms and constructions may suggest themselves to those skilled in the art for accomplishingsubstantially similar results, without departing from the spirit and scope of my invention. I do not therefore wish to be understood as limiting myself to the specific details of mechanism illustrated or described herein, exceptmg as specifically limited in the appended claims.
